|
Planting Instructions
|
- Planting Time: Best planted in spring or fall when temperatures are mild.
- Soil Requirements: Prefers well-drained, fertile soil enriched with organic matter. Thrives in slightly acidic to neutral pH.
- Planting Depth: Plant at the same depth as in the nursery container, ensuring the root ball is level with the soil surface.
- Spacing: Space plants 12-18 inches apart for optimal growth and airflow.
|
Pruning & Maintenance
|
- Timing: Deadhead spent flowers throughout the blooming season to encourage further blooming and tidy appearance.
- Method: In late fall, cut back the foliage to ground level to prepare for new growth in spring.
|
Water Needs
|
- Watering Frequency: Water regularly during the first growing season to establish deep roots. Once established, 'Purple Leia' is moderately drought-tolerant but benefits from consistent moisture during dry spells.
- Soil Moisture: Prefers evenly moist soil; avoid waterlogged conditions to prevent root rot.
|
Light Needs
|
Thrives in full sun to partial shade. At least 6 hours of direct sunlight per day is recommended for optimal flowering and growth. |
Harvesting
|
– Flowers can be harvested when the spikes are about half to three-quarters open for longest vase life
– Cut flower stems early in the morning when moisture levels are highest
– Excellent for fresh cut arrangements – long-lasting blooms in vases
– Can also be dried by hanging upside down in a dark, dry, well-ventilated space
– Deadheading regularly promotes reblooming and prolongs the flowering season |
Fertilizing
|
- Fertilization Time: Fertilize in early spring as new growth begins.
- Fertilizer Type: Use a balanced, slow-release fertilizer or organic compost to promote healthy growth and abundant blooms.
|
Additional Care Tips
|
- Mulching: Apply a layer of mulch around the base to retain moisture, suppress weeds, and protect the roots from temperature extremes.
- Drought Tolerance: While it prefers consistently moist soil, 'Purple Leia' can tolerate brief dry spells once established.
- Pests and Diseases: Generally pest-free; however, ensure good air circulation to prevent any fungal issues in overly humid conditions.
|
Pollination
|
- Pollination Type: Pollinated by bees, butterflies, and other insects attracted to the nectar-rich flowers. The plant is self-pollinating but benefits from cross-pollination.
- Fruit Production: May produce small seeds after flowering, but primarily valued for its ornamental features.
